FOLDING-MACHINE.

Application filed November 7, 1916. Serial No. 130,059.

v specification, like reference characters on the drawings indicatinglike parts in the several figures.

This invention relates to machines. for use in the manufacture of bootsand shoes and is herein illustrated in connection with a ma chine forproducing a socalled French edge.

It is customary in the manufacture of certain styles of boots and shoestQQblIld the edges of parts of the uppers with a strip of fabric. Tothis end such a strip is stitched to the edge of the vamp, quarter orother piece which is to be bound, cement is applied to the strip, andthen the free portion of the strip is folded about the edge of the vampor quarter and pressed down so that the cement will hold it firmly inplace. For convenience the vamp, quarter or other piece will be referredto as a piece of leather and the binding as a strip of fabric. 7

There are two distinct steps in the formation of a French edge after thefabric strip has been stitched to the piece of leather.

First the fabric should be pulled out or drawn back until the stitchessmile, that is, until they can be plainly seen; and secoiid, the portionof the fabric which then extends beyond the edge of the leather shouldbe drawn tightly about said edge and maintained taut while it is laidover onthe margin of the leather. The purpose of this treatment of thematerial is to avoid the formation ofwrinkles or bunches in the bindingstrip.

The general object of the present invention is to provide novel andimproved means by which either or both of the steps referred to abovemay be carried out.

According to one feature of the invention, means are provided fordrawing or pulling the free portion of the binding over that portion ofitself which is attached to the piece of leather or other material.Conveniently the work, which comprises a piece Patented June d, 1918.

of material to which a strip of binding is stitched, may be acted uponby a binding. engaging member which moves over that side of the materialto which the binding is attached and draws back or pulls out the freeportion of the binding until the stitches smile.

According to another feature of the invention, means are provided, inconnection with the means referred to above, for operating upon thepulled-out binding to draw it about the edge of the material and lay itsfree edge down upon the margin of the material on the side opposite thatto which the attached portion of the binding is fastened. Gonvenientlythis means may be a second binding-engaging member similar to the firstbut arranged in such manner that its operative face moves over the sideof the material opposite that to which the binding is attached, theoperative faces of the two binding-engaging members being caused tomove' in opposite directions so that the free por tion of the binding isfirst pulled out and then drawn over the edge of the material.

These and other features of the invention, including certain details ofconstruction and combinations of parts, will be described in connectionwith an illustrative-machine and pointed out in the appended claims.Referring now to the accompanying drawings,

Fig. 8 is a section showing a piece of ma feed operating mechaterial towhich the binding has been stitched,

and

Fig. 9 is a section similar to Fig. 8 but showing the binding in itsfinal, folded position.

Referring first to Figs. 1, 2 and 3, the work 100, which comprises apiece of material such as leather to which a piece of binding such asfabric is attached, is adapt ed to be fed intermittently over a table orsupport 9 by a four-motion feed member presently to be described whichengages the under side of the work and a feed member 11 which engagesthe upper side of the work. The member 11 is pivoted at 13 to a block 15fast to the lower end of a rod 17 and is normally held against a stop 19on said block by a leaf spring 21. The positive feeding of the work isdone by the lower feed member. The function of this upper member 11 ismerely to hold the work against the lower member while said work isbeing moved forward. The member 11 thus swings forward about its pivot13 during the forward movements of the work and swings back again intothe position shown during the pauses between said forward movements. Agage 23 has an operative lower end which engages the edge of thematerial about which the binding is to be drawn and serves by thisengagement to guide the work properly. A preliminary turning member. 25adjustably fastened to the frame of the machine by a screw 27.

give a preliminary turn to theserves to binding as it is fed along.Beyond the gage and the turner are located two bindingengaging membersherein shown as brushes 29 and 31, one below and one above the work toboth of which is imparted rotation in a clockwise direction, theefi'ectof which is to cause their operative portions to travelindirections which are substantially opposite.

The function of the lower brush 29 is to turn back or draw back thebinding (see Fig. 7) tightly so that the margin near the edge which isstitched to the leather will be close to the leather at this point. Itis very desirable that the binding be drawn taut since otherwise therewill occur slackness at the edge of the leather with resultant objectionable bunches or folds. The function of the upper brush 31 is todraw forward the binding about the edge of the leather and lay the freeend or margin of the bindinigt down upon the margin of the leather. A erthe free end or margin of the binding has been thus laid, a presser inthe form of a hammer 33 pounds or resses it firmly into place againstthe margm of the leather. It will be understood that a coating of cementis applied to the binding prior to its presentation to the machine sothat when drawn about the edge of the leather and laid down and pressedinto place itadheres firmly to said leather.

The moving parts of the machine all derive their motion directly orindirectly from a driving shaft 35 mounted-in hearings in the frame ofthe machine and rotated continuously from any suitable source of power.The lower brush 29 has integral shaft 35 through bevel gears 41, 43, anupshaft and bevel gears 47, 4:9. The

right upper brush 31 has fast to or integral with it a bevel gear 51which meshes with a bevel gear 53 fast to an inclined shaft 55 which isdriven from the shaft 35 through a universal joint and bevel gears 57,59. The universal joint is made necessary by the fact that the upperbrush 31 is carried by a rod 61 slidably mo 'unted in bearings in thehead of the machine, said rod being urged downwardly at all times by aspring 63 and limited in -its downward movement by a nut 65 threadedupon the upper end of said rod. By manipulating this nut the normal position of the brush 31 may be varied. It should be noted that the edgegage 23 is alsocarried by the lower end of the rod 61 and is adjustablyheld in place by a screw 67 "which passes through a yoke formed at theupper end of said gage.

The hammer or presser v lower end of a rod 69 slidably mounted inbearings formed in the head of the machine. Fast to this rod are twocollars 71 and 73; and slidable on the rod 69 between the collar 71 anda coiled spring 75 which rests upon the collar 73 is a sleeve 77 whichmay be driven in any suitable manner from the shaft 35, as for exampleby'the crank 79. It will be noted that the collar 73 is adjustably heldin place by a set screw, and that spring 75 through which power isyieldingly applied to the hammer, may be' varied.

The rod 17, by which the upper feed member 11 is carried, is mounted ina manner similar to that of the rod 61, a spring 81 and adjusting nut 83being provided 1 1 which are similar to the spring 63 and nut 65 of therod 61 and have similar functions. The springs 63 and 81 rest uponcollars which are adjustably secured respectively to the rods 61 and 17and may therefore be adjusted. A lever 85 pivoted to the frame of themachine and connected to a treadle rod 87 furnishes means for raisingthe upper brush and the upper feed member when desired. 1

Referring now more particularly to Figs. 4 and 6 in connection with Fig.1, the mech anism for operating the lower feed member will be described.Fast to the counter-shaft 39 is ah eccentric 89 which coiiperates with aslot in a sliding block 91, said block being slidably mounted inanundercut guideway is a rod 99 which in the operation of the ma- 3 y1,2es,eoc

chine swings bodily'about the axis of the counter-shaft 39 and serves tooscillate the collar 95. Actuation of the rod is accomplished throughthe arm 97 which is pivoted at its outer end to the stem of a yoke 101the arms of which embrace an eccentric 103 on the driving shaft 35. Theyoke is oscillated about a pivot 103 the position of which with respectto the shaft 35 determines the amplitude of movement of the stem of theyoke and consequently of the collar 95. The position of the pivot 103may be varied by manipulating a bell-crank lever 105 which is connectedwith the pivot by. a link 107 The lower feeding member 109 is providedwith a stemwhich is fastened to the sliding block 91. With thisconstruction a fourmotion feed is imparted to the member 109, and; theextent of the forward and backward movement may be varied bymanipulating the bell-crank lever 105. The feed mechanism of theillustrative machine has been briefly described since the details of itsconstruction form no part of the present invention.

It is sometimes desirable to snip or slip the margin of the-bindin whichis to be folded over on the leather or example when the edge of theleather has a concavecurvature.

through which the shaft 39 passes. A spring 115 normally holds theknifein inoperative position. To cause the knife to be moved into.operative position and to be reciproca-ted ina path parallel to theshaft 39, a cam 117 keyed to the shaft 39 but slidable thereon isadapted to be engaged and moved forward by a sliding block 119 when afinger-piece 121 is depressed. As long as this will snip or slit theupstanding margin of the binding. When the lever is released, the

slitting ceases.

The operation of the machine is as follows:

The work 100 which comprises a piece of material such as leather towhich a strip of binding such as fabric has been attached by stitches123 comes to the operator in the form shown in Fig. 8, there being acoating of cement on what is shown as the lower face of the binding inthat figure. The operator first roughly pulls the binding out or backand presents the work to the machine with the gage 23 in contact "withthe edge of the leather and the turning member 25 in contact with thebinding as shown in Fig. 3. If desired, the treadle rod 87 may bemanipulated to raise the upper brush 31 and ,the member 11 to permit theforward edge of the work to be placed farther along in the machine;Power is now applied to the machine whereupon the work is fedintermittently over the table To this end a slitting knife 111 is.mounted in a holder 113Vhaving an eye nger-piece is held depressed theknife 9. The gage 23 guides the work, the turning member 25 produces apreliminary turn; the lower brush 29 turns back that portion of thebinding adjacent the stitches and draws it taut, the upper brush 31draws the free edge or margin of the binding tightly about the edge ofthe leather and lays or wipes it down upon the margin of said leatherand the hammer 33 presses the binding firmly into place where it is heldby the cement.

Although the invention has been described in connection witha-particular machine, it should be understood that the invention is notlimited in the scope of its application to the particular machine whichhas been shown and described.
